Engine compartment
There are several reasons a vehicle or engine vibration could
cause an electrical complaint. Some of the things to check for are:
IConnectors not fully seated.
IWiring harness not long enough and is being stressed due to
engine vibrations or rocking.
IWires laying across brackets or moving components.
ILoose, dirty or corroded ground wires.
IWires routed too close to hot components.
To inspect components under the hood, start by verifying the integ-
rity of ground connections. (Refer to GROUND INSPECTION
described later.) First check that the system is properly grounded.
Then check for loose connection bygently shakingthe wiring or
components as previously explained. Using the wiring diagrams
inspect the wiring for continuity.
Behind the instrument panel
An improperly routed or improperly clamped harness can become
pinched during accessory installation. Vehicle vibration can aggra-
vate a harness which is routed along a bracket or near a screw.
Under seating areas
An unclamped or loose harness can cause wiring to be pinched by
seat components (such as slide guides) during vehicle vibration. If
the wiring runs under seating areas, inspect wire routing for pos-
sible damage or pinching.
HEAT SENSITIVE
The owner's problem may occur during hot weather or after car has
sat for a short time. In such cases you will want to check for a heat
sensitive condition.
To determine if an electrical component is heat sensitive, heat the
component with a heat gun or equivalent.
Do not heat components above 60ÉC (140ÉF).If incident occurs
while heating the unit, either replace or properly insulate the com-
ponent.

This DIAL turns the fan ON and OFF, and controls fan speed.
AIR CONTROL DIAL
This DIAL allows outlet air to flow.
TEMPERATURE CONTROL DIAL
This DIAL allows the temperature of the outlet air to be adjusted.
AIR RECIRCULATION SWITCH
OFF position:
Outside air is drawn into the passenger compartment.
ON position (Indicator light ON):
Interior air is recirculated inside the vehicle.
AIR CONDITIONER SWITCH
Start the engine, turn the fan control dial to the desired (1 to 4) position and press the air conditioner switch
to turn ON the air conditioner. The indicator light will come on when the air conditioner is ON. To stop the air
conditioner, push the switch again to return it to the original position.
The air conditioner cooling function operates only when the engine is running.

Lubrication Oil
Name: Nissan A/C System Oil Type R
Part number: KLH00-PAGR0
Maintenance of Oil Quantity in Compressor
The oil used to lubricate the compressor circulates through the
system with the refrigerant. Whenever any component of the sys-
tem is replaced or a large amount of gas leakage occurs, add oil
to the compressor to maintain the specified amount.
If oil quantity is not maintained properly, the following malfunctions
may result:
ILack of oil: May lead to a seized compressor
IExcessive oil: Inadequate cooling (thermal exchange impeded)
Checking and Adjusting
Adjust the oil quantity according to the flowchart shown below.
